Abstract
The present invention pertains to a non-linear, copolymer comprising recurring units derived from vinylidene fluoride (VDF) monomer, at least one functional comonomer and optionally at least one fluorinated ethylenic comonomer. The non-linear fluorinated copolymer comprises from 0.01 to 3.0% by moles of recurring units derived from functional comonomer. The non-linear fluorinated copolymer can be used as electrode binder in batteries.
